You can’t question the legitimacy of Hadiya’s marriage: SC tells NIA

Mangaluru, May 30: Accusing the chief minister B S Yediyurappa led Karnataka government of ignoring frontline warriors against covid-19, Mangaluru MLA U T Khader has demanded immediate release of pending salaries of doctors, lab technicians and nurses hired under the National Health Mission.

Addressing a press conference in the city today, the former minister said that Congress would launch an agitation if the government fails to release the amount immediately.

The non-payment of salaries clearly shows that the government has no concern for the COVID-19 warriors who are serving on a contract basis for two months, he said.

Mr Khader said there are 23,000 personnel hired under the National Health Mission in Karnataka including 600 in Dakshina Kannada district alone.  All of them are waiting for their salaries for the last two months.

“Asha workers were also partially paid for the month of April. If the government had concern towards COVID-19 warriors, they would have paid extra for the doctors, nurses, and other workers who are working tirelessly in the fight against COVID-19 at the grassroots level,” he added.

Mangaluru, Jul 19: In the wake of the COVID-19 lockdown imposed till July 23, streets in the Dakshina Kannada district here bore a deserted look today (Sunday) morning.

The state government had allowed relaxation hours between 8 am to 11 am in the week-long total shutdown. However today there was no relaxation. 

All shops including those selling essential commodities were also seen closed in the district today. Besides, barricades were also seen stationed at different junctures on the road.

As per Karnataka's COVID-19 information portal, a total of 59,652 coronavirus cases have been reported in the state, including 36,631 active cases and 21,775 recoveries. So far, 1,240 people have died due to the infection in the state. 

Dakshina Kannada so far recorded 3,311 covid-19 positive cases and 75 deaths.

London, May 20: The current physical distancing guidelines of 6 feet may be insufficient to prevent COVID-19 transmission, according to a study which says a mild cough in low wind speeds can propel saliva droplets by as much as 18 feet.

Researchers, including those from the University of Nicosia in Cyprus, said a good baseline for studying the airborne transmission of viruses, like the one behind the COVID-19 pandemic, is a deeper understanding of how particles travel through the air when people cough.

In the study, published in the journal Physics of Fluids, they said even with a slight breeze of about four kilometres per hour (kph), saliva travels 18 feet in 5 seconds.

"The droplet cloud will affect both adults and children of different heights," said study co-author Dimitris Drikakis from the University of Nicosia.

According to the scientists, shorter adults and children could be at higher risk if they are located within the trajectory of the saliva droplets.

They said saliva is a complex fluid, which travels suspended in a bulk of surrounding air released by a cough, adding that many factors affect how saliva droplets travel in the air.

These factors, the study noted, include the size and number of droplets, how they interact with one another and the surrounding air as they disperse and evaporate, how heat and mass are transferred, and the humidity and temperature of the surrounding air.

In the study, the scientists created a computer simulation to examine the state of every saliva droplet moving through the air in front of a coughing person.

The model considered the effects of humidity, dispersion force, interactions of molecules of saliva and air, and how the droplets change from liquid to vapour and evaporate, along with a grid representing the space in front of a coughing person.

Each grid, the scientists said, holds information about variables like pressure, fluid velocity, temperature, droplet mass, and droplet position.

The study analysed the fates of nearly 1,008 simulated saliva droplets, and solved as many as 3.7 million equations.

"The purpose of the mathematical modelling and simulation is to take into account all the real coupling or interaction mechanisms that may take place between the main bulk fluid flow and the saliva droplets, and between the saliva droplets themselves," explained Talib Dbouk, another co-author of the study.

However, the researchers added that further studies are needed to determine the effect of ground surface temperature on the behaviour of saliva in air.

They also believe that indoor environments, especially ones with air conditioning, may significantly affect the particle movement through air.

This work is important since it concerns safety distance guidelines, and advances the understanding of the transmission of airborne diseases, Drikakis said.
